If the solution curve y = y(x) of the differential equation y2dx + (x2...
Let's first rewrite the given differential equation:

y^2dx - (x^2 - xy - y^2)dy = 0

To find the solution curve, we can solve this differential equation. Let's separate the variables and integrate:

∫(y^2dx) - ∫(x^2 - xy - y^2)dy = ∫0dx

∫y^2dx - ∫(x^2 - xy - y^2)dy = 0

Let's evaluate each integral:

∫y^2dx = xy^2 + C1

∫(x^2 - xy - y^2)dy = x^2y - (1/2)xy^2 - (1/3)y^3 + C2

Substituting these results back into the original equation, we have:

xy^2 + C1 - (x^2y - (1/2)xy^2 - (1/3)y^3 + C2) = 0

Rearranging the terms, we get:

xy^2 + (x^2y - (1/2)xy^2 - (1/3)y^3) - C1 + C2 = 0

Combining like terms, we have:

(x^2 + 1/2xy - 1/3y^2)y - C1 + C2 = 0

We can rewrite this equation as:

(x^2 + 1/2xy - 1/3y^2)y = C3

where C3 = C1 - C2.

Now, let's find the value of C3 using the given point (1, 1):

(1^2 + 1/2(1)(1) - 1/3(1)^2)(1) = C3

(1 + 1/2 - 1/3)(1) = C3

(4/3)(1) = C3

C3 = 4/3

Therefore, the equation of the solution curve that passes through the point (1, 1) is:

(x^2 + 1/2xy - 1/3y^2)y = 4/3

y2dx - xy dy = -(x2 + y2)dy
y(y dx - x dy) = - (x2 + y2)dy
- y (x dy - y dx) = - (x2 + y2)dy
